To all whom it may concern.-

Be it known that I, CHARLES MARIE J ULES Pn'rm'r, a citizen of the Republic of France, residing in Villeneuve la Garenne, Seine,

Francejfhave invented certain new and useful Improvements in Steering Mechanism for Road Motor-Vehicles, of which the following is a specification.

The chief disadvantage of the various kinds of non-reversible steering mechanism at present employed in the majority ofroad motor-vehicles is that such mechanism. is subjected to relatively rapid wear, owing to its construction, and that this wear is very 5 dillicult to take up, or at anyrate anumber of adjusting operations are required, and frequently the worn or lnltperfect parts have to be replaced or repaired.

The improved steering mechanism which forms the subject of the present invention has not been devised with the object of preventing the possibility of wear, but to permit of readily and perfectly taking up all wear or play which may occur by tightening up a sin- 2 5 gle easily-accessible nut.

The improved steering mechanism is illustrated in vertical section in Figure 1. Fig. 2 is a plan of the rocking frame having two rollers mounted therein, for the purpose explained later.

The steering handle 01' tube A, turned by the driver, carries at its lower end an extension or part B, provided with right and left handed screw-threads a b. These latter may 3, 5 be arranged in different ways. The thread a may be inside the part B and the thread 1) outside, as in the drawings, or both threads may be on the outer or inner face of P5 and disposed one above the other. The adso vantage of the arrangement shown in the drawings, in which the threads are on the outer and inner faces of B, is simply that the mechanism m ade shorter. In this particular case the two screw-threads engage, re

4.5 s ectively, with a nut O and an internal screw f Each of these two parts C and D has an abutment or extension, (lettered c and d, respectively.) These b ear upon two rollers ejj, carried by a small rocking frame or part 6,

which is rigidly connected to a shaft F, piv otally mounted in bearings and carrying at its extremity any'usual 0r suitable means for connecting it to the front wheels. The double-threaded extension B is secured in place in the present case by a large nut I, screwing 5 5 onto the exterior of the casing Gr, a ball-bearing H being fitted between the nut and extension. The nut 1 can be secured rigidly in place after adjustment by means of a jamnut J.

A reference to the drawings will at once show that whatever play may exist between the screws or between. the abutments and the rollers by suitably tightening up the nut I the play may be taken up and all these parts held in good working contact, so as to cause them to bear in the direction in which the force is exerted.

What I claim, and desire to secure by Patent, is

1 A steering mechanism including in com bination a rocking shaft, a pair of members bearing on opposite sides of said shaft respectively, each. of said members having a complete screw-thread, the thread of one being m the opposite direction to the thread of the other, a third member having two screwthreads corresponding respectively to the threads upon 1 the first two members, for pressing said members alternately forward, and threaded means for taking up play, by adjusting the third member toward tl 1e shaft.

2. A steering mechanism for automobiles including in con'ibination a pair of members a and (Z respectively, a rocking frame E, rollers 8 5 c and carried. at opposite sides of saidframe, in the line of movement of said members but unconnected thereto, an internal left-handed screw C carrying said member 0 and an external right'handed scrmv D carrying said 0 member (Z, an intermediate double screw B engaging said screws 0 and 1) and adapted when rotated to move saidscrews O and D in opposite directions, and a nut I securing said screw 13 in place and adjustable to take up 5 play between the members a and d and the rollers c and f. r

p In witness whereof I have hereunto signed my name,'this 24th day of November, 1904,

in the presence of two subscribingwitnesses. 1
